SE2052 DSP Lock-In Amplifier (Dual-channel)

Overview Specifications Ordering Resources

SE2052 Digital Lock-in Amplifier provides an excellent performance within its bandwidth from DC to 400 MHz. With the advantage of the latest digital signal processing technology and high-speed 1GSa/s 14-bit ADC, SE2052 can easily detect the phase and the magnitude of weak signals overwhelmed by various large noises. The performance of SE2052 is as good as other lock-in amplifiers all over the world, even better than them in some certain parameters, such as measurement accuracy, SNR, dynamic reserve, which meets the needs of scientific research and industrial application well.
